Abstract
It consists of culturing at high temperatures, in a medium containing corn steep liquor and ammonium chloride, at suitable concentrations, the superproductive microorganism Bacillus sp. NCIB 12563, thereby recovering and purifying the enzyme alpha -amylase from the culture broth. It is of application in food industry.
